Thermo plastic (thermo = heat) these plastic melts easily and thus be moulded easily and they are soft plastics...examples are polythene..etc
thermosetting plastics (thermo = heat setting = to set)these plastic when burned dont melt easily but forms a black lump these are very hard plastics...some examples are plastic used in switches PVC(poly vineyl chloride...)
